Tilt hinge module for portable terminal and its operation method

The present invention relates to a tilt hinge module for a portable terminal and a method of operating the same, and more particularly, to a tilt hinge module for a portable terminal and a method of operating the portable terminal mounted on the portable terminal so that the movable body of the portable terminal slides with respect to the main body.

In general, personal portable terminals can be classified into a flip method, a folder method, and a sliding method according to an operation method.

Among these, the sliding type mobile terminal generally includes a main body and a mobile body disposed on the upper part of the main body to open and close the upper surface of the main body, and a sliding module for sliding the moving body between the main body and the mobile body is provided.

However, since the movable body is horizontally disposed with the main body in the state where the main body is opened, the sliding type mobile terminal should be inclined at a predetermined angle toward the user when the user views an image through the display unit provided on the upper surface of the movable body.

At this time, the front angle between the middle plate 200 and the lower plate 100 is an angle between the upper surface of the upper plate 300 and the lower surface of the middle plate 200.

And the other end of the slide module 500, that is, the other end of the second connecting member 530 is in contact with the end of the guide hole 410 in the rear.

In addition, as shown in FIG. 13A, the other end of the housing 510 and the other end of the first connection member 520 are inclined in one direction of the guide member 400.

As shown in FIG. 14A, the curved portion of the rotation module 800 is disposed in a neutral state in contact with the side surface of the curved portion of the second cam surface 831.

As shown in FIG. 9, when the upper plate 300 slides backward with respect to the lower plate 100, the other end of the upper plate 300 slides backward along the slide groove 110.

At this time, the upper plate 300 is rotated inclined forward while slidingly moving backwards with respect to the other end of the second connection member 530, that is, the other end of the middle plate 200 together with the guide member 400. do.

The middle plate 200 rotates slightly in a clockwise direction together with the first cam member 820 about one end.

In addition, as shown in FIG. 13 (b), one side end of the housing 510 is moved as the upper plate 300 and the guide member 400 move in one direction, that is, rearward of the upper plate 300. It rotates counterclockwise about one end of the second connection member 530 together with the first connection member 520.

The housing 510 slides along the first connection member 520 in the direction of the guide member 400 to compress the spring 540, and the housing 510 is the second connection member 530. ) Is arranged in a line with the extension line of.

After that, as shown in FIGS. 10 and 13 (c), the upper plate 300 continues to slide backward so that one end of the housing 510 is out of the extension line of the second connection member 530. The one end of the housing 510 is automatically rotated in the sliding direction of the guide member 400, that is, counterclockwise by the elastic restoring force of the spring 540.

The upper plate 300 rotates inclined forward while sliding backward about the other end of the second connection member 530 by the rotational force of the housing 510, and the second connection member 530. When the other end of the contact with the end of the guide hole 410 in front of the sliding of the upper plate 300 with respect to the middle plate 200 is stopped.

Thereafter, as shown in FIG. 11, the upper plate 300 only rotates counterclockwise around the other end of the second connection member 530.

That is, the upper plate 300 only rotates inclined forward with respect to the other end of the middle plate 200.

In addition, the other end of the upper plate 300 continues to slide backward along the slide groove (110).

As shown in FIG. 14B, one end of the middle plate 200 continues to rotate clockwise together with the first cam member 820 to allow the curved portion and the second cam surface of the first cam surface 821 to be rotated. The curved portions of 831 contact each other, and the second cam member 830 slides to the right while compressing the elastic body 840.

Thereafter, as shown in FIG. 14C, when the curved portion of the first cam surface 821 passes through the curved portion of the second cam surface 831 by the rotation of the middle plate 200, the second cam member 830. ) Is slid in the direction of the first cam member 820 by the elastic restoring force of the elastic body 840, the first cam member 820 is automatically rotated clockwise with one end of the middle plate (200). The middle plate 200 stops when the curved portion of the first cam surface 821 is disposed at the side of the curved portion of the second cam surface 831.

In this case, as shown in FIG. 12, the middle plate 200 rotates backward of the lower plate 100 about one end, that is, clockwise, so that the middle plate 200 is moved forward between the lower plate 100 and the middle plate 200. The angle is opened to be an obtuse angle, and the second extension part 220 is disposed at the rear of the lower plate 100.

In addition, the upper plate 300 is tilted forward inclined while moving backwards to fully open the upper portion of the lower plate 100, the other end of the upper plate 300 is the guide member 400 is the slide It stops in contact with the end behind the groove 110.

As such, the other end of the slide module 500 is in contact with the end of the guide hole 410 to stop the movement of the guide member 400 with respect to the slide module 500 when the upper plate 300 is tilted. As a result, the upper plate 300 may be rotated about the other end of the slide module 500 to be inclined more steeply with respect to the lower plate 100.

In addition, the upper plate 300 is tilted inclined forward while sliding so that the front angle between the middle plate 200 and the lower plate 100 forms an obtuse angle when the upper portion of the lower plate 100 is opened. By minimizing the inclination angles of the upper plate 300 and the middle plate 200 as close as possible, the gap between the plate and the middle plate 200 is minimized, and the upper plate 300 slides backward. There is an effect of increasing the range.

In addition, the housing 510 is rotated in the sliding direction of the guide member 400 by the elastic restoring force of the spring 540 to slide the guide member 400, thereby tilting the upper plate 300 semi-automatically There is an effect that the drive is convenient to use.

In addition, the method of operating the tilt hinge module when the upper plate 300 is tilted, the middle plate 200 is rotated to the rear of the lower plate 100 around one end of the lower plate 100 and the middle plate ( The front angle between the openings 200 is an obtuse angle. When the tilt hinge module is fully opened, the middle plate 200 is disposed behind the lower plate 100 so that the upper plate 300 is connected to the lower plate (200). There is an effect that can increase the sliding range along the 100).

In addition, the upper plate 300 is rotatably mounted on the other end of the middle plate 200, the other end is slidably connected to the lower plate 100 by the guide module 600, the upper plate When tilting the 300, the range in which the upper plate 300 slides with respect to the lower plate 100 may be increased, thereby increasing the use area of the upper surface of the main body.

The present invention is not limited to the tilt hinge module for a mobile terminal and its operation method, and can be modified in various ways within the scope of the technical idea of the present invention.

According to the present invention, the other end of the middle plate of the mobile terminal is mounted on the upper plate so that the upper plate slides relative to the lower plate when the upper plate is tilted to increase the use area of the main body of the mobile terminal. .
